2:7 ratio of ethane to O2 = 15:x 9solve for x)
x=52.5 mol O2
Hydrogen and Helium are the first 2 elements
Answer:
1.225g
Explanation:
From the question given,
Volume of diamond = 0.35cm^3
Density of diamond = 3.5g/cm^3
Mass of diamond =?
Density = Mass /volume
Mass = Density x volume
Mass = 3.5 x 0.35
Mass of diamond = 1.225g
